South Africa’s ruling ANC party has been given a pre-election boost.Nelson Mandela has appeared on stage with party leader Jacob Zuma at a final rally ahead of polls on Wednesday. The ANC looks set to win, although polls suggest its big majority will be reduced. Zuma told his supporters: “There is nothing in the constitution that says a massive majority for the ruling party is a bad democracy.” Zuma, recently cleared of corruption allegations, is likely to be elected president in a parliamentary vote if his party wins. But the opposition are doing their best to try to change voters’ minds, accusing the ANC of cronyism and corruption. Helen Zille, leader of the Democratic Alliance, said: “They want to be above the law so they don’t have to go to jail when they commit crimes. But we know that corrupt leaders belong in jail and not in parliament!” The ANC has been criticised for its record on crime, poverty and AIDS, but it maintains it has the right leadership to boost the economy and maintain stability.
